I just found out my cossie block has YBS stamped on it, and not YBB as it's a 2wd engine.
The only info i found about it is they where 1990 spec group A engine blocks?

But if it's 1990 spec, why is it a 205 block?, you would think they would only use 200 block for group A by then?

Also, in what way do these blocks differ from normal 205 blocks?

 

 

Nobody knows what's special about these blocks then?

 

Maybe its an RS500 205 block? Has it got smaller core plugs than a standard 205 block??

 

Werent RS500 blocks stamped YBD??

I'll check the coreplugs anyway, thanks.

 

Was'nt that block standard in a military spec Transit designed to run on kerosene???????Regards Micky
